Application filed August 20, 1908. Serial No. 449,4=7&.

To all whom it may concern:

Be it known that we, STROWBRIDGE B. SEATON and ROY G. TRAVIS, citizensof the United States, residing at Chicago, in the county of Cook andState of Illinois, have in.- vented certain new and useful Improvementsin Printing-Presses, of which the following is a specification,reference being had to the accompanying drawings. I

Our invention relates to printing presses and particularly to presseshaving a reciprocatory motion and adapted especially for the printing oftags and similar articles, although it may be applied to any form-ofpress having a fixed platen and a bed that moves toward and away fromthe platen. Its principal object is to provide a new and improved formof inking mechanism by which the type ward and the backwardreciprocatory move ments of the inking rollers and may be operatedbetween each of the two movements thereby gaining in speed.

It has for a further object the improve ment of reciprocatory printingmechanism in sundry details hereinafter pointed out.

In the accompanying drawings :Figure 1 is a side elevation of the pressin connection with intermittent forwarding, tagforming and cuttingmechanisms. Fig. 2 is a side elevation, being a vertical section on line22 of Fig. 1. Fig. 3 is a top or plan view, being a section on line 33of Fig. 2. Fig. 4 is a plan view, being a section on line 4-4 of Fig. 2Fig. 5 is an enlarged detail, being a partial section on line 55 of Fig.2. Fig. 6 is an enlarged detail, showing the slide carrying'thespring-seated inking-rollers, partially in section. 7 is an enlargeddetail, showing the reciprocating distributing rollers, and theiroperating cam. Fig. 8 is an enlarged detail, being a section on line 8-8of Fig. 2. Fig. '9 is an enlarged detail, being a'view of the gears andsprocket chain which operate the inking drums. Fig. 1 0 is a sideelevation. of the same parts as are shown in Fig. 9, seen from the left.r

Referring to the drawings :-11 indicates the frame of the machine onwhich are mounted the hereinafter described mechanisms.

12 indicates brackets on the frame 11, carbed may be inked by both theforrying thereon arms 13 on which the platen 14 of the press is secured,held-in position by set-screws 15. The platen of course is rigidly heldin place during the operation of the press.

16 indicates arms which are pivoted at one end on a shaft 17 secured inthe outer ends of the brackets 12. The arms 16 support the bed 17 onwhich may be mounted any desirable form, as 18, fromwhich the printingis done.

1'9'indicates a gear mounted upon a stud 20 upon the framework 11 andadapted to be-driven by any suitable power. 21 indicates a gear which issecured upon a shaft 22 which is journaled in the framework 11, the gear21 meshing with the gear 19. 23 indicates a counter-shaft which isjournaled in the framework 11, and is connected by suitable gearing, as2425, to the shaft 22. 26 indicates a shaft which is journaled in theframework 11 and operates to drive the sheet-feeding, tag-forming andcutting mechanism hereinafter mentioned. 272829 indicategears of varyingsizes secured to the shaft 23. 3031-3233 indicate gears of varying sizesslidably mounted on the shaft 26 and adapted to mesh with one or anotherof the gears on the shaft 23 whereby the relative s eeds between theshafts 22 and 23 and the sfiaft 26 may be varied. As these devices areold and well-known in the tag- Inachineart, and form no part of ourpresent invention, it isbelieved thatit is unnecessary to describe themmore fully here.

34 indicates intermittent variable-speed web-feeding mechanism which isoperated from the shaft 26 in any well-known and approved manner. 35indicates a washerforming and applying mechanism which is operated fromthe shaft 26 in any wellknown "manner. 36 indicates a cornercutting andtag-severing mechanism which is operated from the shaft 26 in anywellknown manner. As these several mechanisms form no part of ourpresent invention, and as we are filing a separate application of evendate herewith for sundry Improvements therein, it is believed that nofurther description of them is necessary here, inasmuch as, so far asour present invention is concerned, these mechanisms may be of anyapproved form and description and as they have no necessary connectionwith our present improvements, which may be used without any of thesemechanisms, although 1t1s -especially adapted for use in connection withthem.

37 indicates a gear which is secured upon a counter-shaft 38 and mesheswith a gear 39 on the shaft 22. Upon the other end of the shaft 38 issecured a crank-arm 40 to which is pivotally connected a link 41.

42 indicates a link which is pivotally con nected to the outer surfaceof the gear 37 at the same radial distance from the center of the shaft38 as the pivotalconnection of the link41 with the crank-arm 40. Thelinks 4142 are pivotally connected at their upper ends with the arms 16whereby by the revolution of the shaft 38, the bed of the press 17 isreciprocated toward and from the platen 1 4. 43 indicates aninking-fountain of any approved form which is carried upon the arms'16between the bed of the press and the pivotal connection of said arms 16,and is provided with a fountain roller 44.

45 indicates an ink-distributing roller which is mounted on the upperends of the arms 46 on rock shaft 46 j ournaled in suitable lugs 47depending from the under surface of the arms 16. The other arm 46 of therock shaft rides upon a cam 48 secured to a shaft 49 which is ournaledin brackets 50 bolted or otherwise securedto the under side of the arms16 and extending a suitable distance along the under side thereof.

51 indicates a gear on the shaft 49 which meshes with a gear 52 on theshaft 53 journaled between the brackets 50 and carrying a second gear54.

It will be obvious that by the operation of the cam, the rock shaft 46will be rocked, vibrating the ink-distributing roller 45 from thefountain roller 44 to the ink-drum hereinafter described.

55 indicates an ink-drum which is journaled at the outer ends of thearms 16 upon a suitable shaft 56 upon which is mounted a gear 57. Theink-distributing drum is preferably formed of two parts with the gear 57between them, as hereinafter described. 58 indicates a second ink-drumwhich is journaled between the arms 16 upon a shaft 59 upon which ismounted a gear 60. The inkdrum 58 is preferably like the drum 55 formedof two sections with the gear 60 between them.

61 indicates a gear which is journaled upon a shaft 62 between brackets63 bolted to and depending from the under side of the arms 16 near theirouter extremities. The gear 61 meshes with the gear 57 and operates torotate the ink-drum 55. The gear 54 on the shaft 53 meshes with the gear60 and operates to drive the ink-drum 58.

64 indicates a shaft journaled in the brackets 63.

65 indicates a gear secured to the shaft 64, and meshing with the gear61, and operating to drive the same.

66 indicates a sprocket-wheel secured to the shaft 64.

67 indicates a sprocket-wheel secured to a shaft 68 which is journaledbetween the inner ends of the arms 50.

69 indicates a sprocket-chain which con.- nects the sprocket-wheels 66and 68.

7 0 indicates a gear which is secured to the shaft 68.

71 indicates an arm (see Fig. 9) which. is pivotally mounted upon theouter end of the shaft 68 and depends therefrom.

72 indicates a pin which is secured in the lower end of the arm 71 andcarries journaled thereon a gear 73 which meshes with the gear 70.

74 indicates a sprocket-wheel journalcd upon the pin 7 and either formedintegral with or secured to the hub of the gear 73 so as to rotatetherewith.

75 indicates a sprocket-wheel which is secured upon the shaft 38.

76 indicates a sprocket-chain which connects the sprocket-wheels 74 and75. The gear 70 also meshes with the gear 54 on the shaft 53.

It will be obvious that when the shaft 38 is rotated, the rotation iscommunicated by means of the sprocket-chain 76 to the sprocket-wheel 74and gear 73, thence to the gear 70, rotating the shaft 68, and thus,through the medium of the sprocket-chain 69, to the shaft 64, thence tothe gear 61, rotating the ink-drum 55. The rotation of the gear 70 willalso rotate the gear 54, as above described, which, in its turn, rotatesthe inkdrum 58. The gear 51 and cam 48 will also be rotated, causing thevibration of the inkdistributing roller, thus carrying the ink from thefountain roller 41 to the inkdrum 58.

The swinging arm 71, whose lower end carries the sprocket-wheel 74, willpermit the sprocket-chain to'be kept at proper tension while the gears70 and sprocket-wheel 67 are being moved in an arc with thereciprocation of the arm 16, above described. The arms 16 are provided,upon their outer surfaces, each with a slot 77 which extends from theouter end of the arm 16 to a suitable distance beyond the bed to permitthe reciprocating of the inking-rollers from drum to drum, ashereinafter described.

78 indicates blocks which are slidingly mounted one in each of the slots77 and are adapted to slide longitudinally of the arms 16 in the saidslots 77.

79 indicates brackets which are secured to a suitable portion of theframework of the machine.

80 indicates a rock-shaft journaled in the bracket 79 and provided withan arm 81 secured thereto preferably centrally of the said rock-shaft. v

82 indicates a link which is pivotally connected at one end to thelower'end of the arm 81 and at the other end to a gear 83 journaled upona shaft 84 carried by the framework of the machine and meshing with agear 85 on the shaft 38. By the rotation of the gear 83, the rock-shaft80, through the medium. of the link 82, will be rocked.

86 indicates arms which are secured to the outer ends of the rock-shaft80.

87 indicates linkswhich are pivotally connected at one end to the arms86 and at their other ends to thesliding blocks or carriages 78.

88 indicates pins which are spring-seated, by means of springs 89 in theblocks or carriages 78, and are movable longitudinally of.

themselves in suitable openings in the said blocks 78. I

90 indicates brackets which are secured to.

the upper ends of the pins 88 and whose bottom surfaces are normallyyi'eldingly held against the upper surfaces of the blocks 78 by meansofthe springs89.

91 indicates inking-rolls which are journaled on suitable shafts 91 inthe brackets 90 and extend across nearly from side to side above thearms 16,-that is to say, they are of a length equal to the width of thetype bed 17. The inking-rolls 91 are preferably divided in the center,as is shown in Fig. 3, in the same way as are the ink-drums 55 and 58. i

91 indicates rollers on the shafts 91 and adapted to travel on the uppersurfaces of the arms 16. D

By the vibration of the rock-shaft 80, the blocks 78 will be movedlongitudinally of the arms 16 in the slots 7 7,'carrying theinkingrollers back and forth between the inkdrums 55 and 58, and inkingthe form 18 on the bed 17 with movement in either direction. The rollers91 being spring-seated, as above described, will rise to ride upon theink-drums 55 and 58, as may be necessary and to bear yieldingly upon'theform 18 upon the bed 17 as they pass over it. The inking-rollers 91 willfirst take their ink from the ink-drum 58 to which it is supplied fromthe ink-fountain 43 by means of the fountain roller 44, and thedistributing roller 45, and, inking the type in their passage, willsupply ink to the rotatingink-drum 55, again taking the supply from thatportion of the inkdrum 55 previously supplied by them for their backwardmovement across the typebed. The moving parts are so timed that when thebed 17 is brought into contact with the platen 14, the ink rollers willbe first at one end and then at the other end of their movement, inkingthe form asit rises with each movement in either direction. Suppose, forillustration, the type-bed is in its lower position and the ink-rollersare in contact with the drum 58. As the bed. rises, the inkrollerstravel across the form, inking .the form as it rises, and will bebrought out of the way of the form in contact with the ink-drum 55 asthe impression occurs.

Both distributing ink to and getting ink from the drum 55 as the bed.falls, the inkrollers as the bed rises will again travel across itssurface from the ink-drum 55 toward the ink-drum 58, inking it whiletraveling in that direction. As the form is thus inked by theink-rollers while traveling in either direction, and the inking-rollersbrought out of the way of the form at the end of each. movement ineither direction, it is obvious that the ink-rollers have to travelacross the form only once for each impression.

. Inasmuch as the speed of a reciprocating press of this kind is limitedvery largely by the speed of the inking-rollers, it is obvious that thepress may be worked at considerably higher speed where the impressionoccurs between each movement in either direction of the inking-rollersthan it can where the inking-rollers have to travel across the bed andback again out of the way with each impression.
